An all-star lineup including Britney Spears, Mary J. Blige, Gwen Stefani, Pink, Imagine Dragons, Adam Lambert, and many more have teamed up to release “Hands,” a tribute to the 49 victims of the shooting at the Pulse Orlando nightclub last month.

The song was written Justin Tranter, Julia Michaels, and BloodPop. It was produced by Tranter, BloodPop, and Mark Ronson. According to a statement from Interscope, money from the sale of the song “will benefit Equality Florida Pulse Victims Fund, the GLBT Community Center of Central Florida, and GLAAD.”

“Like the rest of the world I woke up to the news that morning and was horrified and sad and scared,” he said. When the songwriter asked The Center Orlando, an area LGBT community center, if they needed help, he says they responded, “We need as many hands as we can possibly get.”

The song’s performers recorded their parts separately, wherever and however they could.

“Mary J. Blige recorded in New Orleans,” Tranter explained. “Britney Spears in Thousand Oaks, I think. Pink in Santa Barbara. MNEK recorded at home in London. Selena recorded in her studio bus. Dan Reynolds recorded in his home. Adam Lambert was in Luxembourg. Ty Herndon the country star was in Spain. Kacey Musgraves, Nashville. Everyone just got it done.”
